Many people only know that there are vacuum casting equipment, but they don't know much about the working process and structure of vacuum casting equipment. The following is a brief introduction of Suzhou flute Electromechanical, a manufacturer of vacuum casting equipment.

Pouring process of vacuum oiling equipment: time for material pretreatment (inserting lining material with adhesive or semi conductive rubber, evacuating and drying filler, melting and evacuating solid epoxy resin, evacuating curing agent) → material mixing (first mixing filler and epoxy resin, and then evacuating resin), Then mix with curing agent) → pre curing (the casting material is cured in the curing furnace, and the curing degree is more than 80%) → demoulding (maintain an appropriate temperature to release the product and quickly load the product)) → post curing (the product is centrally cured after demoulding, improve the curing degree and release the internal stress) → post-treatment (clean the product gate, mold locking seam and other defects) → check the packaging.

Pouring process of vacuum oil injection equipment: data preprocessing (insert coated with binder or semi-conductive rubber, filler vacuumized and dry, solid epoxy resin melted and vacuumized, and curing agent vacuumized) → data mixing (first mix and vacuumize the filler and epoxy resin at one time, and then mix with curing agent) → pre curing The first mock exam is to solidify the castables in the curing oven, curing to more than 80%. Then, the mould is removed (the product is released at the right temperature and the product is quickly loaded into the next mold). Then, the curing is made (after the product is released, the curing degree is increased, the internal stress is released), the postprocessing (cleaning the product gate, the mold closing and other defects), and the inspection of the packaging.

Compared with traditional insulation materials, epoxy vacuum casting products have many common advantages:

① No air gap or less air gap, the electrical insulation performance of the product is excellent;

② Casting molding has good fluidity, natural filling cavity and good product uniformity;

③ Due to the good electrical performance, the product can be miniaturized and the host structure can be optimized;

④ The product can be made into complex shapes and formed at one time, with good integrity of metal inserts and insulation materials;

⑤ Good weather resistance and can be applied to indoor and outdoor areas;

⑥ The product is solid, flame-retardant, safe and convenient to use.

However, the process also has shortcomings:

① There is no reinforcement data in the system, the mechanical properties are poor, and there is fracture in the application of the main engine;

② There is a certain stress in the product, and the product has the risk of cracking when the stress accumulation is released;

③ It is easy to have various defects in appearance quality.
